[RP-PPPoE] rp-pppoe.so in kernel mode

[Palasamudram, Chaitra (NSN - IN/Bangalore)]

Hi Adrian,

Were you able to look into this issue... do you know how can I make the pppoe_channel defined in the plugin so that the call back function are executed ? 

Thanks 
Chaitra

Hi Adrian,

I was not able to work on this till now. Now I am able to load the plugin and I can see that "Options" structure is passed to PPPD and it adds to the extra_list. But still I am not able to make it work. 

My question is, when the control comes to rp-pppoe to start the Discovery procedure.. I can see that PPPD is sending LCP Req directly. I don't see that rp-pppoe.so is getting kicked in for pppoe flow. 

In the code I see that there are call back functions when the pppoe_channel gets defined but not sure how this whole this works... can you please help again.

Thanks a lot.

Regards
Chaitra

I think that path for PPPD binary is for rp-pppoe to know where to 
invoke ppp binary in your system.
